The École Polytechnique, commonly known as Polytechnique or l'X, is a prestigious grande école in France specializing in science, technology, and engineering. Founded in 1794 during the French Revolution, it has played a pivotal role in French higher education and scientific advancement. The institution is located in Palaiseau, near Paris, within the Paris-Saclay technology cluster, having relocated from its original site in the Latin Quarter of central Paris in 1976.
The École Polytechnique was established on September 28, 1794, by the National Convention as the École Centrale des Travaux Publics, initiated by mathematician Gaspard Monge and Lazare Carnot. This creation occurred amid political and economic turmoil at the culmination of the Age of Enlightenment, aiming to train engineers and scientists for the needs of the French Republic, particularly for public works and military applications. The school's name was changed to École Polytechnique in 1795.
In 1804, under Napoleon I, the institution was militarized, granting its students the status of military cadets. This reform aligned the school with national defense objectives, and it adopted the motto "Pour la Patrie, les Sciences et la Gloire" (For the Homeland, Science, and Glory). Throughout the 19th and 20th centuries, École Polytechnique alumni, known as polytechniciens, contributed significantly to French industry, science, and politics, including figures like Henri Poincaré and Alfred Nobel connections through influence.
The school evolved in the modern era, expanding its academic offerings. It began awarding master's degrees in 2005, doctorates in 1985 (formalized later), and bachelor's degrees in 2017. In 2019, it became a founding member of the Institut Polytechnique de Paris, enhancing its research and international collaborations. As of 2025, celebrating over 230 years, École Polytechnique maintains its military affiliation under the French Ministry of Armed Forces, with students undergoing initial military training.
École Polytechnique offers rigorous programs in mathematics, physics, chemistry, biology, economics, and computer science, emphasizing interdisciplinary approaches. The flagship Cycle Ingénieur Polytechnicien is a three-year engineering program admitting students via a highly competitive national exam. International students can join through the Bachelor of Science or specialized master's programs, many taught in English.
Research is a cornerstone, with centers in applied mathematics, mechanics, and data science. The school ranks highly globally; in the 2026 QS World University Rankings, it placed 41st, particularly excelling in engineering and technology. It fosters innovation through incubators and partnerships, producing leaders in AI, energy, and defense sectors.
The modern campus in Palaiseau features state-of-the-art facilities, including laboratories and a library housing historical collections. Students, numbering around 2,000, benefit from a diverse, international community. As military cadets, they receive stipends and participate in parades, such as the annual Bastille Day event. The school's traditions include the famous "X" cap and a strong alumni network influencing French society.
